Retrieve employee SSN data via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee record (employee ID 66). It is part of a broader platform offering various pay-per-request APIs across data analytics, AI/ML, finance, and utility categories, all settled via the x402 protocol on the Base network using USDC.
The endpoint is live and returns a standard x402 payment challenge (HTTP 402) when called without payment. It accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The price is $0.02 per request (20,000 base units of USDC, which has 6 decimals). Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base L2 network, with a maximum timeout of 300 seconds.
Note: This endpoint purports to return personally identifiable information (SSN). The actual nature and legitimacy of the data returned is unknown — it may be synthetic/demo data or it may raise serious regulatory and legal concerns. There is no documentation, OpenAPI schema, or example responses available beyond the x402 challenge metadata and the provider's landing page. The broader platform advertises a uniform $0.02/request pricing model with no API keys, no rate limits, and instant access.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation, no example responses, and the endpoint claims to serve highly sensitive PII (SSN) with no explanation of data provenance or compliance. The docs, pricing, and API pages all return only 'Connect wallet' with no useful content.
Warnings
- —Endpoint claims to return Social Security Numbers — highly regulated PII. Verify legal compliance before use.
- —No documentation, OpenAPI spec, or example responses available.
- —Data provenance unknown — may be synthetic/demo data or may pose serious legal risk.
- —All documentation pages (docs, api, pricing, README) returned only 'Connect wallet' with no substantive content.
- —No input schema documented; unclear what POST body (if any) is expected.
